RESUMO

The fast advance in wireless communication technologies and satellites service have enabled the appearance of a new paradigm in computer science, called mobile computing. Solutions to problems in mobile computing are different from those to traditional distributed systems, due to a set of inherent characteristics of mobile environment, like: mobility, frequent disconnection, low bandwidth, high latency, reduced storage capacity-limited battery life and small screen sizes. Therefore, although the basic issues in the traditional distributed environment are well understood, a review of some of these issues with respect to the mobile environment are useful to comprehend those characteristics. In this dissertation it is proposed a new transaction model and a new checkpoint protocol for the mobile environment. The transaction model and checkpoint protocol form an adequate framework for data consistency to mobile computing environment
